The inclnerator CORSlSlJSIOf' anunner container- 1: WlllOll'lS" coneshaped at its lower portion and: termlnatesln' acylindrical? portion atthe-topi: The: container" 1s mounted upon and supported by a base 2and1s suits ably-- attached thereto by means of rivets or bolts '3extendinw throu h: the bottom flan ed port-ion-thereot aslndicated Rti4:1 The base 7 portion 2 consistsot: a cylindrical portion provided atitsupper end with an in-turned annular flange-upon which the container 1ismounted. Within the opening inpthe flange of the baseislocated l inany's-uitableimanner a movable: grate '5 as shown clearly in Figs.-

The base 2' is also" providedfwith a door' 6 which admits-of accessto'the ash pit within the-base; The'outer jacket 7 of cylindrical tormsurrounds the base'2' and extends upwardly to' substantially the samelevel as the top of the container 1; This-outer jacket on shell mayterminate substantially at the' top of the base'2 but for convenience itis extended downwardly to the bottom of the base;- The annular spacebetween the tops of? the outer jacket and theinnercontainer'is closedbyanannular plate or cover-8 which is provided with a collar orflue-extension Qthrough Whichthe-products of combustion passout- Wardlytoa= chimney or directly into the" atmosphere: Theopeningrin'thetop ofthe irrner container is closed by meansof a pivoted cover 10. Thegarbage is introduced into the inner receptacle or containerthroughitsopen' top and when-thecover10 is placed in position the upper end isclosed substantially" air-tight: The inner container ispr0= vided withan o'penin'gll which permits the products of combustion to pass from thein= ner container into the: sp ace" between: it and the'outer shell orjacket. This opening is located near thetop of the'apparatus. Theinner'contain'er is also provided'witli acollar for extension 12: whichextends outwardly through'the-wall'of the-outerjacket andpro vides-anopeningfor' the insertion of a burner or burners 1'3: These burners maybe de signed for use ofoil-inwhich'case'they are of the'injector type orif gasis-used as a fuel they are preferably of the Bunsen type.

Between'the inneran'dthe outer shells are located two baffles ordivision plates l twhich extend'fromthe' cover 8-d0wnwardlyand'terminate a short distance above the top of the base 2leaving'openings for'the passage-ofthe products of combustion underthe-lower ends of: the same. Thesebaflies arelocated on opposite sidesof the incinerator and divide the space'bet'weenthe two shells into twochambers. The opening 11 admits the productsof combustion into' onechamber from which they pass downwardly under the lower ends of thebaflle plates and thence upwardly to the-flue connection 9; The baflies14 may be cast integral with theinner shell I asindicated in Fig. 4 andmay be attached to the outer shell by means of suitable rivets or screwsas indicated at 15. It will be noted that the opening 11 and the collaror extension 12 for the reception of the burners and the door 6 arelocated on one side which may be termed the front of the incinerator andthe.

flue outlet 9 is located on the opposite side.

The incinerator may be made either wholely of cast or wrought iron orother suitable metals but it has been found desirable to make the innercontainer, the base and the top and cover of cast iron and the outershell or jacket of wrought iron. The battle plates of course may be madeas separate elements and suitably attached to the inner container andthe outer shell. The top cover 8 and thebase may be held together bymeans of rods or bolts in any suitable manner.

In the operation of the incinerator the earbage is placed in the innercontainer and the cover 10 closed. The burners are then nited and ignitethe garbage in the inner container. It will be apparent that thatportion of the container 1 adjacent the burners and particularly thelower "portion. of the container will be heated to an extremely hightemperature by reason of the burners and by reason ofthe heat developedby the combustion of the garbage. The products of combustion 'which arecharged with objectionable and offensive odors it permitted to escapeare conducted through the openin 11 downwardly over be highly heatedPortion of the outside of the inner container, under the lower ends ofthe baflles l I and thence upwardly to the flue 9. The in passing fromthe highly heated portion of the inner container on their way to theflue will be subjected to such a. temperature as to substantiallyeliminate the oli'ensive odors produced thereby. It will thus be seenthat a new process for the elimination of oiiensive odors arising fromburning garbage has been devised as indicated above. The gases whichpass through the opening 11 are passed di rectly over the highlyrheatedlower portion of the inner container which subjects them to suchtemperature as to practically elin inate the oiiensive odors arisingtherefrom.

It will be apparent that theproducts of combustion of the burninggarbage are not allowed to mix with air until they have been subjectedtothe re-heating process by be ng forced to pass in close contact withthe l ighly heated lower portion of the inner container. In fact theproducts of combustion do not receive any air until they reach theoutlet 9 except of course what. is introduced through the connection 12and passes upwardly through the burning garbage.

In the apparatus described the gases formed by the combustion of thegarbage are brought into contact with the hot portion of the incineratorand so are re-heated to a point which prevents the discharge of existingoffensive odors. It is an essential that the products of combustion beprevented as de' scribed from coming into contact with fresh air such asmight come through the grate from the ash pit. For this reason theannula-r space between the container and the outer container 7 is closedsubstantially air-tight.

It will be obvious to those skilled in the art that various othermodifications may be made in my device Without departing from the spiritof my invention and therefore I do not limit myself to what is shown inthe drawings and described in the specification but only as set forth inthe appended claims.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is 1. In an incinerator, an inner shellprovided with a grate, an outer shell, a cover engaging the upper edgesof both said shells, diametrically opposed baflies extending from saidcover downwardly between and in contact *ith said shells, a base closingthe space between the lower ends of said shells, said battlesterminating short of said base, a burner casing extending through theouter shell and into the inner shell above said grate, said inner shellhaving an opening in its side wall near the top and directly above saidburner casing, said outer shell having an outlet opening at its topdiametrically opposite said burner casing whereby the products ofcombustion will be conducted from the inner shell near its top downwardsover the heated portion of said inner shell, under the lower ends ofsaid bafiles thence upwardly to said outlet.

2. In a garbage incinerator, two coaxial shells closed at the top, theannular space between said shells also being closed at the bottom, agrate in the bottom of the inner shell, said inner shell having anopening near its top into the space between said shells and anotheropening near its bottom for the reception of burner means, a burnercasing extending from the outer shell to the inner shell and fitting inthe burner opening in the inner shell, said outer shell having a flueopening at its top diametrically opposite the openings in said innershell. a pair of vertical battles extending from the top of said shellsdownwardly and terminating short of the bottom of said annular space.whereby products of combustion are led from said inner shell downwardlyunder said bat fies and thence upwardly to said flue opening.
